Technical specifications cover aspects like operating frequencies, RF power output, frequency stability, and more.

Using the Lectrosonics DPR - A Digital Plug - On Transmitter is straightforward. First, connect your microphone or line - level source to the standard XLR connector. You can then set the desired tuning frequency within the 470.100 - 607.950 MHz range, with 100 kHz or 25 kHz steps. Select the output power of 25 or 50 mW according to your needs. To set up quickly, use the IR port with an IR - enabled receiver. When it comes to power, insert two AA batteries (lithium is recommended). You'll see the status indicated by the multi - color LED. For audio quality, you can adjust the gain control and the low - frequency roll - off. When using the recorder, insert a microSDHC memory card. Note that the transmitter should be operated within the temperature range of - 20 to 50 degrees Celsius (- 5 to 122 degrees Fahrenheit). For maintenance, keep it clean and dry. Check the battery regularly and replace them when the power is low. Also, make sure to update the device via the SD card to keep it running smoothly.
